This fall's refinery maintenance season is expected to be heavier than in years past because refineries ran at such high rates during the summer.
Refineries typically conduct maintenance in the autumn and spring when demand for gasoline, diesel and heating oil is relatively low.
More refineries than typical have scheduled maintenance for the next few weeks.
Retail averages could rise during this maintenance period.
Much of this maintenance should wrap up by December, which would allow a steady decline in gas prices later in the year.
Uncertainty about global oil demand is reportedly impacting the price of crude oil.
